gets, fgets - get a string from a stream
char *fgets(s, n, stream)
Gets reads a string into s from the standard input stream stdin. The string is terminated by a newline character, which is replaced in s
by a null character. Gets returns its argument.
Fgets reads n-1 characters, or up through a newline character, whichever comes first, from the stream into the string s. The last charac-
ter read into s is followed by a null character. Fgets returns its first argument.
puts(3S), getc(3S), scanf(3S), fread(3S), ferror(3S)
Gets and fgets return the constant pointer NULL upon end of file or error.
Gets deletes a newline, fgets keeps it, all in the name of backward compatibility.
